EXCERPTS:
"If by "capitalist" you mean someone who cares more about his own profit than yours; if you mean someone who cares more about providing for his family than providing for yours; if you mean someone who trusts that he is a better caretaker of his own interests and desires than a bureaucrat he's never met, often in a city he's never been to: then we are all capitalists. Because, by that standard, capitalism isn't some far-off theory about the allocation of capital; it is a commonsense description of what motivates pretty much all human beings everywhere....
The problem with socialism is socialism, because there are no socialists. Socialism is a system based upon an assumption about human nature that simply isn't true. I can design a perfect canine community in which dogs never chase squirrels or groom their nether regions in an indelicate manner. But the moment I take that idea from the drawing board to the real world, I will discover that I cannot get dogs to behave against their nature--at least not without inflicting a terrible amount of punishment. Likewise, it's easy to design a society that rewards each according to his need instead of his ability. The hard part is getting the crooked timber of humanity to yield to your vision.
